I did comment on this, but when the actor hits the wall it will not go through it, but when it starts to reverse, or faces the other way and drives forward, it goes through the walls as if it was driving normally.

It is best to first do an action (turn or move), then check for an obstacle. If one is encountered, then undo the action. That way, you are always not over an obstacle after each act step.

Thank you, this fixed it.
